And the Ulduar tests continue on the PTRs.
Yesterday was the Flame Leviathan, and today (in the US) was Ignis the Furnace Master. Both have been downed and were bugged or too easy. Ignis was downed both in 10 and 25 man version, even after some bug fixing that was literally giving you a win at 30% life. Clearly I hope that Ulduar won't be that easy, Hodir seemed fine, the other since seem too easy. Grats anyway to all the guilds that work hard on the PTR to test these mobs and help Blizzard tuning them right.
Flame Leviathan info with a complete description of the vehicles on MMO Champion.
A lot of info can be also found on WoW Insider.
Ignis the Furnace Master abilities and info on World of Raids.
A nice review of the boss on WoW Insider too.
